Vacuum Operation
- Turn off the blue valve and red valve.
- Power on the instrument. Then make sure that the LCD displays the vacuum test status. If not, press the Mode button to switch It. (When the instrument is turned on, there may be 10 digits in the high and low pressure display area. At this time, press the zero button long until it returns to zero.)
- Press the unit button to adjust the reading unit.
- Connect the instrument to the refrigeration system as shown. (pay attention to the direction of the refrigerant flowing!!! ) (Connected clamp-on temperature probes will not affect the operation..)
- Turn on the blue valve and red valve, and start the vacuum pump.
- After the extraction is completed, first turn the blue valve and red valve to the closed state, and turn off the power of the vacuum pump.
- At this time, the mode can be adjusted to the leakage test state to observe whether there is leakage in the refrigeration system pipeline. If there is any leakage, the location of the leakage point can be further checked for maintenance; if there is no leakage, the next step of refrigerant filling operation can be performed.
Refrigerant Filling and Pressure Inspection
- Turn off the blue valve and red valve.
- Power on the instrument. Then make sure that the LCD displays the pressure test status. If not, press the Mode button to switch It. (When the instrument is turned on, there may be 10 digits in the high and low pressure display area. At this time, press the zero button long until it returns to zero.)
- If the temperature probe accessories have been connected to the instrument, the real-time temperature will be displayed. If not, no display of it.
- Press R+/ R- buttons, Unit button and ℃/℉ button to select the tested refrigerant and reading display respectively.
- Connect the instrument to the refrigeration system as shown. (pay attention to the direction of the refrigerant flowing!!! )
- Turn on the refrigerant valve and gently press the pressure release valve to vent the air in the connecting hose.
- When the refrigeration system stops, turn on the high pressure valve (red valve) and fill it with a certain amount of refrigerant and then shut the valve quickly.
- Run the refrigeration system, and turn on the low pressure valve (blue valve). and fill with the refrigerant into the refrigeration system. Vacuum operation is required if it is filled initially or in full with refrigerant. Refer to the section on vacuum operation.
- After the filling is completed, shut the low pressure valve (blue valve) and refrigerant valve. Let the refrigeration system running.
- Shut down the refrigeration system, make sure all valves are turned off, then disconnect the instrument between the refrigeration system and source. Do not remove the high pressure valve connection until the pressure drops to the safe point. Then turn off the instrument.
Note: The filling operation of different equipment or refrigerants may vary. Please read carefully the relevant specific operation requirements for filling operation, so as to avoid damage to users or equipment caused by improper operation!!

Common Problems
1、Low battery power supply
The refrigerant gauge has low power sign. When it is displayed, it means the battery power is insufficient. At this time, the battery should be replaced as required in order to avoid affecting normal use.
2、Damaged refrigerant hose or valve stem
Please check the pipe fittings and the hoses before testing. Once any damage is found, please replace it immediately.
3、Failure of refrigerant filling
There Is a valve core In the refrigerant inlet of the refrigeration system. When connecting the instrument, pay attention to the two terminals of the hoses. Connect one terminal with a core to the refrigeration system, while another terminal without a core to the refrigeration gauge.
4、Potential leak points
Every hose terminal comes with a nylon pad limited to a certain life of use. Overuse or other situation will make it defective, which result in leakage.
The instrument refrigerant inlet (the middle port of the Instrument ) has a port with a valve core, which is used to discharge the air in the connecting pipe by pressing the valve core after connecting the refrigerant source.
5、Product does not work properly
Please let us know and we can reship brand new gauge, hoses, temperature clamps or suitcase.

Temp clamp broke after second use. Looking to see if they sell replacements. Otherwise this thing is great. It does all the calculations for you. No more converting psi to temp and subtracting temp etc. love this thing.

This digital gauge set works well and appears to be accurate. I used my trusty old analog gauge set on a car and then put this gauge on the same car. The measurements from both gauges read alike. This doesn’t mean these gauges are laboratory accurate, but great for anyone working on HVAC systems. The great thing is that these gauges work for so many different types of refrigerants. The quarter turn shut off valves are quick and easy to turn. The center hose has a schrader valve which, allows for purging air out of the hose before filling up the system with refrigerant. The backlight function is great for working in attics and basements with low light.The included hoses seem to be good quality and have nice, built-in wing nuts to help give leverage when tightening and loosening the hose ends. Great for DIYers that don’t want to spend too much money.

Automatic subcooling and superheat calculations!... need i say more other than I wish it included the required batteries... I am like a kid and get very frustrated when the batteries are not included

Odd they rate these hoses at 3000PSI (Ha!) yet at 78 PSI they leak at the crimp.The hose itself MAY take that pressure but no point in all that if the crimp joint is garbage!Sent it back and bought same type of unit from another seller and bought a Yellow Jacket hose set!Sadly the yellow Jacket hoses cost more than this manifold set!

Firstly the hoses and fittings are R12 and doesn't come with enough adapters. The 3rd vehicle I used it on the high pressure hose split at the end where hose is clamped to the threaded end. Do not buy.
